# device_sim_trigger_method Trigger a discoverable method on the selected Verse device via Python API. Agent View of the PolicyLayer registry record for `device_sim_trigger_method`. HTML page: https://policylayer.com/tools/quangdang46-uefn-verse-mcp/device-sim-trigger-method ## Facts - Tool: `device_sim_trigger_method` - Server: Uefn (`quangdang46/uefn-verse-mcp`) — https://policylayer.com/tools/quangdang46-uefn-verse-mcp.md - Homepage: https://github.com/quangdang46/uefn-verse-mcp - Risk category: Execute (High risk) - Registry record: grade F, identity unverified - Server rate-limited: no - Parameters: 0 - Recommended policy verdict: Rate-limited ## Example call (MCP tools/call, JSON-RPC 2.0) ```json { "jsonrpc": "2.0", "id": 1, "method": "tools/call", "params": { "name": "device_sim_trigger_method", "arguments": {} } } ``` ## Why device_sim_trigger_method is rated High This tool executes arbitrary methods on Verse devices through a Python API bridge. The effects are runtime-dependent on the specific method invoked and its arguments, making it an Execute category risk. From the tool's own definition: "Tool description states 'Trigger a discoverable method on the selected Verse device via Python API.' The verb 'trigger' combined with 'method' execution via Python API indicates the tool runs code or invokes methods whose effects depend on which method is…" ## Use case AI agents invoke device_sim_trigger_method to trigger actions in Uefn. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Uefn: ```json { "version": "1", "default": "deny", "tools": { "device_sim_trigger_method": { "limits": [ { "counter": "device_sim_trigger_method_rate", "window": "minute", "max": 10, "scope": "grant" } ] } } } ``` ## Other tools on Uefn (142) - `delete_actors` — Destructive — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/delete-actors.md - `delete_asset` — Destructive — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/delete-asset.md - `shutdown` — Destructive — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/shutdown.md - `snapshot_restore` — Destructive — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/snapshot-restore.md - `tag_remove` — Destructive — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/tag-remove.md - `undo` — Destructive — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/undo.md - `batch_exec` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/batch-exec.md - `blueprint_compile` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/blueprint-compile.md - `bulk_mirror` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/bulk-mirror.md - `device_call_method` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/device-call-method.md - `device_sim_generate_proxy` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/device-sim-generate-proxy.md - `execute_python` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/execute-python.md - `focus_selected` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/focus-selected.md - `niagara_spawn_system` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/niagara-spawn-system.md - `postprocess_spawn` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/postprocess-spawn.md - `refresh_device_catalog` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/refresh-device-catalog.md - `run_tool` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/run-tool.md - `scatter_along_spline` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/scatter-along-spline.md - `scatter_props` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/scatter-props.md - `select_actors` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/select-actors.md - `select_by_class` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/select-by-class.md - `sign_spawn_bulk` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/sign-spawn-bulk.md - `smart_spawn` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/smart-spawn.md - `verse_build` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/verse-build.md - `verse_template_deploy` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/verse-template-deploy.md - `zone_spawn` — Execute — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/zone-spawn.md - `bulk_randomize` — Other — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/bulk-randomize.md - `pattern_circle` — Other — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/pattern-circle.md - `pattern_grid` — Other — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/pattern-grid.md - `pattern_line` — Other — https://policylayer.com/tools/quangdang46-uefn-verse-mcp/pattern-line.md - …and 112 more: https://policylayer.com/tools/quangdang46-uefn-verse-mcp.md ## For agents This record is a snapshot.
